Friends don't let friends punch women.
But the best part is that his punch didn't even put her down. Her knees buckle a little, but then she's back up.
Good question - does he get any legal points in his favor that she threw the first (albeit lame) punch? Does it matter that she's a she?
If that does matter, should prosecutors take into account that a guy in a fight with another guy is a skinny weakling?
